I/O Lines
Clocks
Interrupts
The pins used for interfacing the PWM may be multiplexed with the I/O Controller lines. The pro-
grammer must first program the I/O controller to assign the desired PWM pins to their peripheral
function. If I/O lines of the PWM are not used by the application, they can be used for other pur-
poses by the I/O controller.
The clock of the PWM (CLK_PWM) is generated by the Power Manager. This clock is enabled at
reset, and can be disabled in the Power Manager. It is recommended to disable the PWM before
disabling the clock, to avoid freezing the PWM in an undefined state.
The PWM counters can be fed by a Generic Clock (GCLK). This is a high frequency clock which
is asynchronous to CLK_PWM.
The PWM interrupt line is connected to the Interrupt Controller. Using the PWM interrupt
requires the interrupt controller to be programmed first.
